Exterior Deck Construction
Exterior Deck Construction
(OP)
I have a project I'm designing for a camp that is a two story dining hall and meeting room building. The lower level is used for the meeting rooms and the upper level will be the dining room. The floor plan calls for a deck outside the dining room along two sides. The deck is about 18 feet wide. The architect would like the deck to be waterproof so that people can come out of the meeting rooms below but not get wet of it is raining. This tends to eliminate the traditional wood deck framing because water will leak through the gaps in the decking.
I looking for suggestions for a deck detail that can have an exterior exposure and provide a barrier for water penetration. This will have high foot traffic as it will be a place for groups to congregate. The main building interior floor framing will be steel beams/joists and concrete slab. I'm thinking this should be a sandwich type deck with a concrete slab, membrane and topping slab. I would appreciate any specific information on membrane and detailing specifications for the assembly. If the framing remains steel then I'm concerned about corrosion of steel. I could use a good epoxy enamel or perhaps galvanizing. Galvanizing sounds expensive.
Thanks for your help.

This deck has been used for the roofs over turnpike toll booths in PA and NJ.

Timing has a lot to do with the outcome of a rain dance.

Some can take heavy traffic, but it will still be a mainrenance item though.

I was happy with Dryjoist http://www.wahoodecks.com/dryjoist/
Otherwise, I typically, design for 4" concrete, corrugated steel deck, and steel beams.
I've also seen a lot of failing decks that have used less than 3" of concrete.
